About SyncEvolution
===================
SyncEvolution synchronizes personal information management (PIM) data
via various protocols (SyncML, CalDAV/CardDAV, ActiveSync). It syncs
contacts, appointments, tasks and memos. It syncs to web services or to
SyncML-capable phones via Bluetooth.
Binaries are available for Linux desktops (using GNOME Evolution, or
KDE's Akonadi), for Maemo (Nokia N900, N9) and Sailfish OS (Jolla
phone).
About 1.5.1
===========
Maintenance release. Binaries now also get compiled for Debian 8.0
"Jessie".
Details:
* avoid time zone issue with Funambol server
The Funambol iCalendar 2.0 parser fails to handle time zones
with quotation marks around the TZID value, which is something
that SyncEvolution started to add in 1.4.99.3. While it is valid
to quote like that, it is not necessary, so avoid quoting in
this case to restore interoperability.
* syncevo-http-server: stop using deprecated twisted.web.error (FDO #90419)
This has become a real problem for example on Fedora 22 where the
old name is no longer available.
* syncevo-http-server: use TLS instead of SSLv3
This fixes a potential security risk and connection problems with clients
that don't support SSLv3 anymore.
* syncing: avoid segfault for invalid text inside items (FDO #90118)
As reported by Canonical, syncing fails if data items contain
text which is not correct UTF-8 in one of the fields that
SyncEvolution logs in the command line output (like SUMMARY of
a calendar event).
That is because the byte string coming from the item is passed
unchecked to the D-Bus implementation for transmission via D-Bus. But
D-Bus strings must be correct UTF-8, so depending on the D-Bus library
in use, one gets a segfault (GIO D-Bus, due to an unchecked NULL
pointer access) or an "out of memory" error (libdbus, which checks for
NULL).
SyncEvolution now replaces invalid bytes with a question mark in its
output while preserving the rest of the text.
* file backend: log item manipulation
Extracting a meaningful description of each item from the Synthesis
engine when updating and adding items is easy to do for items of
certain known types (contacts and calendar items).
* command line: preserve log prefix of target side of local sync
In some cases, the prefix which was supposed to be embedded
in the log messages from the target side of a local sync got
lost on the way to the command line tool.
Primarily this affected the added/updated/deleted messages, as in:
[INFO remote@client] @client/addressbook: started
[INFO remote@client] updating "Joan Doe"
[INFO remote@client] @client/addressbook: received 1/1
* compile fix: use ${PKG_CONFIG} instead of pkg-config.
This fixes the build on Exherbo that only has prefixed versions of
pkg-config.
* WebDAV: handle 403 during Google OAuth authentication
When sending an access token with insufficient scope (for example,
because the Ubuntu Online Accounts service definition was incomplete,
as documented in FDO #86824), Google responds with a 403 "service
denied" error.
This is now dealt with by retrying, just as for a transient 401 error.
* CalDAV: more efficient "is empty" check (FDO #86335)
Since 1.4.99.4, syncing WebDAV collections always checks first
whether there are items in the collections. This was partly done for
slow sync prevention (which is not necessary for empty collections),
partly for the "is the datastore usable" check.
However, this did not take into account that for CalDAV collections,
the entire content gets downloaded for this check. That is because
filtering by item type (VEVENT vs. VJOURNAL) is not implemented
correctly by all servers. So now all CalDAV syncs, whether incremental
or slow, always transfered all items, which is not the
intention (incremental syncs should be fast and efficient).
This release adds a more efficient isEmpty() check: for simple CardDAV
collections, only luid and etag get transferred, as in
listAllItems(). This is the behavior from 1.5.
For CalDAV, a report with a filter for the content type is used and
the transfer gets aborted after the first item, without actually
double-checking the content of the item. This is different from
listAllItems(), which really transfers the content. This extra content
check would only be needed for some old servers (Radical 0.7) and is
not essential, because reporting "not empty" even when empty is safe.
* WebDAV: send Basic Auth via http in some cases (FDO #57248)
It turned out that finding databases on an Apple Calendar server accessed via
http depends on sending Basic Auth even when the server does not ask for it:
without authentication, there is no information about the current principal,
which is necessary for finding the user's databases.
To make this work again, sending the authentication header is now forced for
plain http if (and only if) the request which should have returned the
principal URL fails to include it. This implies sending the same request
twice, but as this scenario should be rare in practise (was only done for
testing), this is acceptable.
* Ubuntu Online Accounts: support plain text credentials
The backend for UOA was rewritten by Alberto Mardegan and now also
can use plain username/password credentials stored in UOA.
* various compiler error and warning fixes
Source, Installation, Further information
=========================================
http://syncevolution.org/blogs/pohly/2015/syncevolution-151-released
Source code bundles for users are available in
https://download.01.org/syncevolution/syncevolution/sources
and the original source is in the git repositories
http://cgit.freedesktop.org/SyncEvolution/
i386, lpia and amd64 binaries for Debian-based distributions are
available via the "stable" syncevolution.org repository. Add the
following entry to your /etc/apt/source.list:
deb https://download.01.org/syncevolution/apt stable main
The GPG key for the repository needs to be imported as root with:
apt-key adv --keyserver keyserver.ubuntu.com --recv-keys B2EC3981
Then install "syncevolution-evolution", "syncevolution-kde" and/or
"syncevolution-activesync".
These binaries include the "sync-ui" GTK GUI and were compiled for
Ubuntu 10.04 LTS (Lucid), except for ActiveSync binaries which were
compiled for Debian Wheezy, Ubuntu Saucy, Ubuntu Trusty an Debian
Jessie. The packages mentioned above are meta-packages which pull in
suitable packages matching the distro during installation.
Older distributions like Debian 4.0 (Etch) can no longer be supported
with precompiled binaries because of missing libraries, but the source
still compiles when not enabling the GUI (the default).
The same binaries are also available as .tar.gz and .rpm archives in
https://download.01.org/syncevolution/syncevolution/. In contrast
to 0.8.x archives, the 1.x .tar.gz archives have to be unpacked and the
content must be moved to /usr, because several files would not be found
otherwise.
After installation, follow the
http://syncevolution.org/documentation/getting-started steps.

Is it possible to configure syncevolution to have the "local" side be an
ical or vcard file (for events or contacts)? If not, does anyone know of an
application that would allow me to sync caldav/carddav to files like this?

Hi all,couple of years ago we discussed the advantages of syncevolution and SyncML over opensync and support for KDE4.Back then I was not sure if I'll stick to KDE, but since I preferred to stay on TDE for various reasons.
However I am missing one essential part - the sync with the mobile phone(s) in TDE, so I was wondering what I can do about it, being already convinced that the only one could help me is syncevolution.I would also write backends for TDE if necessary, as I already did for opensync, but the integration of the code into the syncevolution build and gui are still a mystery for me.May I ask for your opinion please - what would be the steps or send me web links to docs as I'm getting lost in the documentation?1. Is there a way to sync with TDE without writing backends for TDE? I ask this in the bluetooth/usb context.
2. Where do I start and what process should I follow to integrate the code into the build and in the gui?3. In the backend part I see kde, kcalextended and akonadi for kde4 - why was that split up - I mean, I see what is in the code, but why the split?
thanks in advance
regards

Hello,
I just realized that the syncevolution fails to build against
libical 2.0.0. The problem is synevolution's extract of
icaltz-util.c/.h, referencing extern const char *ical_tzid_prefix;
This variable had been made private and there is no way to get to it
from the outside of libical (the added icaltimezone_tzid_prefix() is
not exported in the libical library).
I do not know the rationale with the icaltz-util extract in the
syncevolution, but I'd say it's time to get rid of it when new-enough
libical is used for the build. What do you think?
I placed a lame workaround in my build and defined the missing variable
with the value copied from the libical 2.0.0 sources. I know it doesn't
scale and can easily break in the future, but I expect that there will
be done a proper fix upstream meanwhile and I'll be able to drop the
workaround once the fix will be released.
Bye,
Milan
